The roughly 80-minute speech was punctuated with both calls for unity and jabs at the opposing party, as well as some emotional asides featuring guests of the White House and the formidable freshmen class of Democrats.

Here are seven noteworthy moments from Trump's 2019 State of the Union:

Democratic women have their moment

In a speech that prompted numerous glares and groans from Democratic lawmakers, the president sparked an unexpected moment of joy from the women who helped propel Democrats into the House majority in last year's midterms.

"No one has benefited more from our thriving economy than women," Trump said, noting that the demographic filled 58 percent of newly created jobs in 2018.

The chamber stood and cheered again when the president noted there are more women in the workforce than at any other point in history.

"Don’t sit yet, you’re going to like this," he continued. "And exactly one century after Congress passed the constitutional amendment giving women the right to vote, we also have more women serving in Congress than at any time before.”

More than 100 women were elected to Congress in last year's midterm elections, setting a record, and setting pace for Democrats as the party picked up more than 40 seats in the House to retake the majority.

Trump warns against 'partisan investigations'

The president fired a warning shot at Democrats in the room who have pledged to look into the president's finances, White House security clearances and other areas.

“An economic miracle is taking place in the Untied States, and the only thing that can stop it are foolish wars, politics or ridiculous partisan investigations," Trump said.

"If there is going to be peace and legislation there cannot be war and investigation," Trump said. "It just doesn’t work that way."

Pelosi responded in real time through one of her Twitter accounts, saying that Congress "has the responsibility to exercise oversight of the other branches of government. We would be delinquent in our duties if we failed to provide the necessary oversight."

Sorry, sir. But Article 1 of the Constitution is the legislative branch. And it has the responsibility to exercise oversight of the other branches of government. We would be delinquent in our duties if we failed to provide the necessary oversight. #SOTU

Democrats have pledged to use their new House majority to conduct rigorous oversight and investigations into the Trump administrations. Lawmakers have highlighted the president's financial ties, the administration's foreign policy decisions, its handling of migrants family separations and its response to Hurricane Maria as areas of interest.

Democratic leaders have said they intend to carry out impeachment proceedings against Trump only if there is broad consensus on the subject.

The president and his allies have sought to dissuade Democrats from focusing on investigations, warning that doing so could undermine any bipartisan legislative efforts.

Attendees sing to Holocaust, synagogue shooting survivor

One of the more upbeat moments of the evening came when the chamber broke into a rendition of “Happy Birthday” to celebrate a survivor of the Tree of Life Synagogue shooting.

Judah Samet attended Tuesday’s address as a guest of the White House. Trump acknowledged him in the crowd and noted it was his 81st birthday.

Attendees then broke into song, with Trump mock-conducting from the dais.

“Thank you!” Samet shouted.

“They wouldn't do that for me, Judah,” Trump joked, before continuing on with his speech.

New York lawmakers last month passed legislation expanding women’s access to abortions. The bill allows women to get abortions after 24 weeks if their life or health is threatened by the pregnancy, or if the fetus is not viable.

In Virginia, Democrats put forward a bill that would allow third-trimester abortions if the mother's health were threatened. The legislation stirred debate, but has not been put up for a vote. It has been overshadowed in recent days by controversy surrounding Gov. Ralph Northam (D).

Woman granted clemency by Trump moved to tears

Alice Marie Johnson, a former prisoner who was granted clemency by Trump last year, was moved to tears as the president highlighted her story as an example of the need to reform the criminal justice system.

“Alice’s story underscores the disparities and unfairness that can exist in criminal sentencing and the need to remedy this total injustice,” Trump said.

Johnson, who was seated with the president's family as a guest of the White House, received a standing ovation and became visibly emotional.

"Alice, thank you for reminding us that we always have the power to shape our own destiny," Trump added.

Johnson wiped tears from her eyes and she returned to her seat.

Trump commuted Johnson’s sentence last June after reality star Kim Kardashian West brought her case to the president's attention. The 63-year-old great-grandmother was serving a life sentence on nonviolent drug and money laundering charges.

Trump decries socialism

Trump prompted raucous chants of "USA" from Republican lawmakers when he pledged that "America will never be a socialist country."

After the president spoke of the dire state of affairs in Venezuela, he shifted his attention to the rise of progressive ideas on the domestic front.

"We are alarmed by the new calls to adopt socialism in our country," Trump said, eliciting "boos" from some in the room.

"America was founded on liberty and independence, and not government coercion, domination and control," Trump added. "We are born free and we will stay free."

Critics of those policies have equated the suggestions to socialism, and pointed to the ongoing crisis in Venezuela as an example of potential consequences.

Trump digs in on immigration

Trump made his push to tighten immigration laws and build a wall along the southern border a central part of his lengthy speech, but stopped short of declaring a national emergency after teasing the possibility in recent days.

“No issue better illustrates the divide between America’s working class and America’s political class than illegal immigration," Trump said. "Wealthy politicians and donors push for open borders while living their lives behind walls and gates and guards.

"Meanwhile, working-class Americans are left to pay the price for mass illegal migration — reduced jobs, lower wages, overburdened schools and hospitals, increased crime and a depleted social safety net," he added.

Trump's desire to build a wall along the southern border has been at the heart of a standoff with congressional Democrats. The president's demand for $5.7 billion for the structure triggered the recent 35-day government shutdown.

The president had suggested in recent days that he may declare a national emergency to direct construction of the wall, a measure that would likely draw swift legal challenges and rebukes from GOP lawmakers. He did not do so on Tuesday night, but emphasized his commitment to erecting a barrier.

"In the past, most of the people in this room voted for a wall. But the proper wall never got built. I will get it built,” Trump said as GOP lawmakers stood to applaud.

The wall, he said, would be a "smart, strategic, see-through steel barrier" built in areas of need identified by border agents.
